Rockets 2 Racecars Promotional Loop

Drag Race to Mars Engineering Design Challenge

Design a capsule to land on Mars, just as NASA engineers have. As the capsule rushes through the atmosphere, it is speeding towards the surface, headed for a crash landing! You need to use the drag of the atmosphere to slow the capsule down. Using the materials described, design an apparatus that will create enough drag to allow the capsule to have a soft landing on the surface.

Please note, you will be judged on the speed or rate of descent. Use the data sheet provided to record that measurement after each test trial. Also record notes on modifications to your design as you work.

Enjoy the challenge of working through the engineering process

Rocket Racers

There are many variables that affect a car’s ability to travel a straight path, let alone speed around a racetrack. Test your ability to control these variables and build a car that will travel the farthest distance. For further information contact Bonnie Murray at Bonnie.Murray@NASA.gov

Bernoulli's Law Activities

When you’re traveling at speeds of 200 miles an hour, it’s important to understand that faster moving air creates lower pressure! Air traveling around a curved surface speeds up, creating an area of low pressure. Demonstrate this fact with these simple experiments.

Shuttle Tire Activity

Shuttle Tire Activity http://www.aeronautics.nasa.gov/pdf/space_shuttle_tires_5_12.pdf

Tires, track surfaces and coefficient of friction are all huge considerations for crew chiefs and team mechanics. Tire pressure specifically, is a factor used to increase the cars handling ability and fuel efficiency. In this activity you’ll compare various tires and learn how to calculate tire pressure as it is affected by temperature. For further information contact Bonnie Murray at Bonnie.Murray@NASA.gov

Rocket Wind Tunnel Activity

Rocket Wind Tunnel Activity http://www.nasa.gov/audience/foreducators/topnav/materials/listbytype/Rocket_Wind_Tunnel.html

Understanding how airflow around an object is affected by the objects shape is valuable information for both race car drivers and rocket designers. Being able to measure this variable provides valuable data, and that’s where wind tunnels come in handy. Both models and full scale cars have been tested in the wind tunnels at Langley, and are now tested in full scale tunnels at team garages on a regular basis. I this activity you’ll see how you can build your own small scale tunnel and do some testing of your own.

There are also several simple aerodynamics and wind tunnel activities is the Sci Files Guide : Sci Files Guide pdf

FoIlSim Activity

FoIlSim Activity http://www.grc.nasa.gov/WWW/K-12/freesoftware_page.html

FoilSim is interactive computer simulation software that demonstrates airflow around various shapes of airfoils. The Airfoil View Panel, is a simulated view of a wing being tested in a wind tunnel with air moving past it from left to right. Students change the position and shape of the wing by moving slider controls that vary the parameters of airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area. The software displays plots of pressure or airspeed above and below the airfoil surface. A probe monitors air conditions (speed and pressure) at a particular point on or close to the surface of the airfoil. The software calculates the lift of the airfoils, allowing students to learn the factors that influence lift.

A technical paper describing the details of the mathematical method used in FoilSim is also available. http://www.grc.nasa.gov/WWW/K-12/airplane/FoilTheory.pdf

Fluttering Fun Activity

Proper weight and balance are essential for the safe operation of a race car, just as they are for an aircraft. The distribution of weight, and the location of the car’s center of gravity affect the stability and handling of the car as it travels around the track. The center of gravity is the point where the weight is balanced, the point through which the force of gravity acts and about which the car is balanced.

Bug O'Copter Activity  - Page 1.                  Page 2.

As we’ve seen, moving air can be a real pick me up, or it can be a huge drag! Race car designers need to reduce drag as much as possible to allow for the fastest speeds, and the best gas mileage. Experiment with the effects of drag using this simple paper copter. For further information contact Bonnie Murray at Bonnie.Murray@NASA.gov
